How to connect to another machine via Telnet?

Rohan Pande 445

Hi,

I am trying to connect to another machine (Windows OS) from a machine (Windows OS) via the Telnet protocol. But I fail in connecting the machine.

My aim is that after connecting the machine, I should be able to run an application on the destination machine from source machine.

Error:
Microsoft Telnet> open 10.20.16.222

Connecting To 10.20.16.222...Could not open connection to the host, on port 23: Connect failed

I have tried downloading the telnet from command line and also checked in the Windows Features whether "Telnet Client" is enabled or not. But no luck. Can somebody help?

The target server would need to listen on TCP port 23.

You should not be using Telnet for remote management - it's not secure.

Use PowerShell Remoting instead. More at https://learn.microsoft.com/en-us/powershell/scripting/learn/ps101/08-powershell-remoting?view=powershell-7.4

I understand that the protocol is a bit old and unsecure but still wanted to know.

Can you tell how this can be achieved?

You would need to install a third party Telnet server (for example, https://www.georgiasoftworks.com/product/telnet-server-windows#:~:text=The%20GSW%20Telnet%20Server%20for,Technical%20support%20is%20also%20included.). Windows Server no longer includes this component as part of the OS.

But there is some documentation from Microsoft should this not work? I tried running that command from command line. But I didn't get any dialog box coming up.

This is documentation from 15 years ago. Telnet Server was removed from the OS in Windows Server 2016
